[Shmakovka narzan mineral water in the treatment of chronic pyelonephritis in children]. / Shmakovskii narzan v lechenii khronicheskogo pielonefrita u detei.

The impact of "Pasechnyi" spa of the Shmakovka health resort on the circadian urinary output, renal excretion of magnesium, calcium, nonorganic phosphorus, oxalates, uric acid, phospholipids, acido- and ammoniogenases, daily fluctuations of urinary pH was studied for the first time in 65 children with chronic pyelonephritis. In the presence of spa treatment the authors revealed a 75-100 per cent increase in the circadian urinary output, urinary excretion of magnesium, uric acid, ammonia, titrated acids, a decrease in the levels of calcium, oxalates, nonorganic phosphorus and acidification of the urine at 9 o'clock in the morning mainly in children with primary pyelonephritis and at 9 and 6 o'clock in the morning in patients with concurrent uricosuria. Other parameters were not significantly different from those in the controls. Acidification of the urine in the presence of high uricosuria resulted in crystalluria of urates and oxalates in 26.31 per cent of patients with the concurrent urate diathesis. The water of Shmakovka mineral springs is recommended for patients with primary pyelonephritis, phosphaturia and calcium oxalate crystalluria with alkaline reaction of the urine and unjustified for those who suffered from urate diathesis.
